Low-Impact Processor for Dynamic Runtime Power Management

Low-Impact Processor for Dynamic Runtime Power Management

This article presents a method of modifying a processor so that it can estimate its own power and energy consumption in parallel with application execution. The authors have applied the method to an existing 32-bit processor and demonstrated it on a range of benchmarks. The system adds only a small...

Zusammenfassung:This article presents a method of modifying a processor so that it can estimate its own power and energy consumption in parallel with application execution. The authors have applied the method to an existing 32-bit processor and demonstrated it on a range of benchmarks. The system adds only a small increase in average power consumption and chip area.
